Talkback Mountain is a segment in the show where a number of listeners call in to briefly discuss a chosen topic with the hosts, or share a related anecdote with the listeners. In this segment there are also 'dovetails', where Kavalee will ask callers a follow-up question that runs counter to the main phone-in topic. This was a semi-regular concept also used on Triple M's drive-time program The Shebang in 2004-2005, which featured 'sub-questions' after the main question, such as 'what's your favourite banshee?'.

The segment begins with a theme tune featuring a sample of the song Detachable Penis and a phone tone ringing effect and a sheep bleating. An alternative theme tune which is used is a sample of the song Tainted Love, and a range of sound effects and yodeling. More recently, the show's sketch producer, Matt Dower, has been creating a new Talkback Mountain theme for each show, including one based on the Sonny & Cher song I Got You Babe and one based on the Jive Bunny version of the Hawaii Five-O theme.
